We've heard some hard-to-believe diagnostic tall-tales over the years. And, to be honest, we've invented a few pretty good ones, ourselves.

Mark "Smoky" Hanson from Fort Collins, Colorado recently wrote us and reminded us of the age-old blinker-fluid-change scam. (Has anyone ever really fallen for that?) Mark also hinted that it might be time for us to have our muffler bearings repacked.

Thanks, Mark. We seen a few transmission rebuilds in your future. Real soon.
